The camera looks like a good B-Cam for my purposes, how does the zoom lens compare to a APS-C Sensor like a 550D, would the zoom range be similar to my 550D with the 24 - 70 I have or will it have a slighter longer range because of the crop?

The range is 24-75mm in stills mode. In video mode it is about 26-82mm.

The crop on your 550D makes your focal lengths longer. The 24-75mm (26-82mm in 4K mode) on the lx100 are adjusted for their 35mm equivalent. The actual focal length of the lx100 lens is more like a 10-30mm or something.

Thanks although I actually ended up finding out on my own by accident. I was looking for something else in the menu and saw something that might resolve the issue I was having and after I set it to on, presto! That's good because I would have had such a big headache trying to record a lot of things in Sao Miguel, Azores and having to record first to see how my adjustments are and then go back and delete those parts in order to not have too much junk on the card.

Liking the pictures out of the LX100 but the 15min record limit in 4K has meant that it's no good for half of my stuff (interviews & concerts) - annoying that Panasonic crippled a good little camera.

The limit is indeed a drawback, but Panasonic didn't "cripple" the camera as if they were conspiring to protect their pro cameras or something: it is an overheating issue resulting from keeping the camera small and compact and allowing 100Mbps given the limitations of current technology. The tiny Samsung Galaxy S5 has a 10-minute limitation for 4K video for exactly the same reason (even though a lower bitrate).

I decided to also upload my Sao, Miguel, Azores video to Vimeo in case people wanted to download the 4K file. I took away over 3 minutes worth of footage just to sort of make it flow better. People can always watch the YouTube version to see everything.
